German-Tunisian Omaima Abdi, 34, was arrested in Hamburg during a sophisticated police operation.

ISIS experts say Abdi was a key member of the death cult’s propaganda machine darkly called the “Mumsnet for jihadi brides”.

Her hate-packed phone fell into the hands of an Arabic-speaking reporter.

Among the contents were e-mails recruiting Western brides for jihadi brothers. Photos of one of ISIS’s most fanatical fighters were also on the phone.

According to The U.K. Sun, Abdi married German rapper Denis ‘Deso Dogg’ Cuspert after her first husband was obliterated in an allied air raid in Syria.

Her second husband blew his brains out as the walls caved in on the caliphate.

But before he was taken off the board, he orchestrated the videotaping and distribution of images of British hostages David Haines and Alan Henning.

He also allegedly lured hundreds of young German Muslims to join ISIS.

He told a German reporter he turned to ISIS because of racism in his homeland: “I grew up with racism. Though my mother is German, some teachers back then would call me ‘Negro’ and treat all Muslim kids bad.”

Bizarrely, since her return to Germany, Abdi has been working as an event planner and interpreter, according to The Sunday Times.

The Times said Abdi is also a central figure of the Free Our Sisters in the U.K. which supports jailed female terrorists. She was also active in trying to convert non-Muslims.
